Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602666, here are decompositions:

29 + 8602637 = 8602666
179 + 8602487 = 8602666
227 + 8602439 = 8602666
257 + 8602409 = 8602666
269 + 8602397 = 8602666
353 + 8602313 = 8602666
467 + 8602199 = 8602666
509 + 8602157 = 8602666

Showing the first eight; more decompositions exist.
